Ok so I just paid a local gm mechanic friend of family to replace my 87 L 98 intake manifold....car runs awsome..hiweer its always ran powerful and sounded great but now once its wrmed up and you get into the gas I think I here valves rattling ...could this just be a timing issue?? Even though it got knock sensors? Any help is appreciated ..thks :doh:li

When your friend did the manifold he probaby did not set the timing right. Check the ign timing with a timing gun.........
